SlJilIIIllN4 S. HALL, OF PORTLAND, CONNECTICUT, ASSIGNOR TO THE PICKEIItINRt GOVERNOR C0., 0F PORTLAND, CONNECTICUT, A CORPORATION.

Be it known that AI,SfrneHxiN Sa, HALL, a citizen of the United States,.residing at Portland, in the county of Middlesex andv State of Connecticut, have invented a new and useful Improvement in Universal J oints and I do hereby declare the following, when. taken iii connection with the accompanying drawings and t-he letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute partof this specification, and rep resent, inl Figure 1 a View in side elevation of a .uni- Versal joint for transmitting motion constructed in 'accordance with my invention, a

portionof the coupling-ring being broken i shown in away andshown in vertical section. Fig. 2 a View of the joint in vertical section on the `line v -J) of F ig. 1 and looking in the direction of the arrow o, the heavy bearing pins, however', being shown in elevation. Fig. 3 a detail view showing two of .the hearingpiiis in elevation and the supporting disk which 'is inserted into longitudinal slots formed in their inner ends, the disk being lace in one of the pins, and the other pin seing drawn away from it to better show its slot. Fig. 4 an end view of one of the pins looking at its inner end. Fig. 5 a ,detached plan view of the supporting washer. Fig. (3 a brokenv plan view of one ofthe yoke-arms of one ofthe joint members.

My invention relates to an'iniprovcd universal joint designedfWi-th particular reference to being used in niotor vehicles, such as automobiles and trucks, the object being to yproduce a simple, compact and convenient the outer ends of heavy bearing-pins 4 the outer ends of which are virtually flush with the periphery of the ring 2 and the inner ends of which are adapted to be supported UNIVERSAL Jorn@ feachaipen theotherab .iorifniiigtfthemnv tut-.zitieren i. at

As shown also, the inner ends of thel ins are formed with longitudinal slots 6 or the reception of a siipportiner and centering disk 7. I do not, howeverflimit myself' to any particular way of supporting and re'- inforcing the inner ends of the bearing-pins 4 which in themselves are very hea and. amply su ported at their outer ends n the ring 2. or do" I limit myself to any particular method of securing the pins 4 in the ring 2. As shown they are secured inplace by fastening pms 8 driven into holes 9 ex- -tending transversely through the ring. the

pins taking into transverse notches 10 in lthe outer ends of the pins. As thus constructed y and arranged the middle portions of the pins forni heavy bearings or journals for. the yoke-arms 11 of the joint-members 12, the

said yoke-arms 11 being formed with circu`ll lar openings 13 just large enough in diame t ter for the reception of the respective bear- .ing-pins 4. It will be understood that the respective j oint-members 12 with their yokearms are introduced into the ring 2 from the opposite sides thereof, one joint-member be in turned a quarter turn vwith respect to the ot er, whereby the openings 13 in the yokearms 11 are' registered with the respective bearing-pins 4. which are then introduced intol the said openings and pushed home therein. The pins 4 are then fixed in 'place by means of the fastening-pins 8 or other devices. i

My improved device reduces the number of parts to the minimum, and I am enabled on account of its simplicity, to employ very heavy bearing-pins 4 and to support them so solidly that the joint is able to transmit great power. j t

I claim 1. `In a universal joint., the combination with a coupling-ring havinfr radially arranged bcaring-openings, o bearing-pins fastened4 at their outer ends in the said openings and having their inner ends slotted. a centering-piece introduced into the slots in the inner ends of the pins, and two joint members formed with yoke-arms adapted to be inserted into the ring from the o posite sides thereof and receiving the midd e por tions of the bearing-pins.I

2.`In a universal joint, the combination I l with va coupling-ring having radially arranged vbearing-openings, of bearing pins fastened at their outer ends in the said open- 5 ings and having their inner ends slotted and beveled, and n centering-disk introduced into the slots in the inner lends of the said pins for'centering andsupporting theirlsaid inner ends, and two joint-members each having two yoke-arms formed with openings re- 10 ceiving the middle portions of the said pins. In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
